Application filed '.ecember 12, 1921.

To all whom it may 0021061101/ Be it knoivnthat l, EUGENE VILUOME, acitizen ot`,the United States7 residing at St. Louis,lvlissouri, haveinvented a neiv and useful Improvement inv Squares, ot which thet'olloiving is a specilication.

rlihis invention relates to an improvement in squares, and consists inthe novel construction hereinalfter described.

An object of the invention is to lprovide a square having one arm inthe. t'orm ot a straight edge rule' and the other arm Acornectedtherewith, the second arm comprising pivoted sections arranged Ato moveon avertical axis to either sidepreserving rthe cont-inuity otl the sidefaces ot' the arm.

Additional advantages :ot the. construction Will be apparent trom thetolloiving detailed description thereof, taken in connection with theaccompanying drawing in which Fig. 1 is an elevationv ot the completesquare.

Fig. 2 is a plan view. f

Fig. 3 is a vertical'sect-ion taken substantiullyjon the line '3s-3 otFig. al..

Fig. et is a cross section taken on the line alf-tot Fig. 1.

Fig. 5 is a cross section taken on 5-5 ot'Fig. 1.

Fig. G is a application of an irregularly The square ot' particularlyadapted for as work on irregularly shaped patterns t'or castings or thelike, and has many special 'teatures and advantages adapting it tor suchwork as an instrument ot precision.

In the embodiment of the invention illustrated in the drawing the arm 1thereot is in the torni ot a straight edge rule having graduations onone tace and having a slot in the rear tace thereot'. The other arm ismade up oit a plurality oit sections, the section joined to the rulebeing in the torni ot ay block 3 having a slot 4. therein thatconstitutes a seat for the edge ot the rule 1 and into which said rule 1is fitted.

The block has a cut-out portion 5. ln order to clamp the block 8 inconnection With the rule 1 a releasable clamp device comprising a lockmember including a. body (3 having an inwardly extending flange or bead7 is mounted in an opening 8 through the Wall ot the block intermediateot the cut-out portion 5 or slot 4 the bead T engagthe line diagrammaticvieiv showing shaped piece ot ivork.

ingY in the slot 2 in the back tace of the rule. Said lock member isprovided with an actuator including a. stem 9' upon which is mounted a.member 10 having a cam tace 11. The member 1'() is revoluble onthe stem9 and is heldA trom displacement therefrom by a Washer 12. The washer 12is ot the 'familiar split type in Which a slot runs from the hole to oneside ot the Washer, permitting the Washer to be applied to and removedit'rom thestem 9 While the member 1t) is on the stem. The Washer'engages a. reduced portion ot vthe stem 9,I the inner end ot whichseats in a recess in an extension 17 ot' the block 3 (Figs. 3 and e). Aspring 13v is nested in a cavity in the outer face of the member 10 andbears against the Washer 12. The calm tace otv the member 10 camsagainst an inclined Wall 14 otY the cut-out portion 5. Thus as themember 10 is rotated the lock member is moved inwardly and outwardly tolrelease and to clampthe block 3 in connection with the rule 1 so thatthe block 3 may be adjusted yto any desired longitudinal position on therule and, alter the adjustment is eftt'ected, may be clamped :tromdisplacement. It Willg, of course, be understood that the specific 'formo-t'clamp device described may be modified and other forms may beemployed it desired.

As illustratedin the drawing the second sec-tion ot the adjustable armis in the form ot a link including a. body portion 15 havinghorizontally extending flanges 1G, the flanges 16 being rounded at theends. A

rounded extension 17 at the end of the block 2l is so t'ormed as to bereceived between the i'l anges 16 and has an opening therein to registerwith openings in the flanges 16 to receive a tapered pivot pin 18. A.cavity 19 is Ytorrned in the body ot' the link 15 in which mounted a.plate Qt), said platebeing actuated outwardly by a spring Q1 in thecavity back of the plate. The front edge of the plate is beveled asindicated at Q2, theedge Q2 abutting against the rounded surface ol' theextension 17. The extension 17 has a vertical slot termed therein, sothat when the link and block are in longitudinal alinement they will belocked in adjustment. As the plate 2O is actuated against the roundedsurface ot the extension 17 a suiicient frictional engagement ismaintained so as to hold the block and link in relative adjust ment Whenthe link is moved from the long'n tudinal adjustment.

The arm of the square may include any desired number of linksconstructed as described, it being' understood that the termi-V nal linkinstead of having a projection has a plane vertical face as indicated at28.

A square constructed in accordance With the invention has numerousapplications and may be employed on a great variety of Work.

ln Fig 6 one application is illustrated inv which the square isl shownapplied to a cy# lindrical structure 24: having a reduced cylindricalextension 25,. The flexible arm of the square maybe curved about thereduced cylindrical "portion 25 holding the rule section in a perfectvertical plane.

All of the edgesv of the flexible section of the rule are arranged inthe saine plane so that the square may be used for ruling straightvlines, regardless of the contour of the `object to which Y it isapplied. The square is also useful by reason of the flexible extensionsfor squarmg up on Work having parallel surfaces Where the surfaces are1n such, close yproximity that it would be im-V possible toinsert thelateral arm of the s uare, if the arm was fully extended.

4ll any otheruses Will be found for the device, particularly greataccuracy. v

I am aware that the invention jmay be modified in Various particularsWithout deon Work that requires parting from the spirit and scopethereof( .l do not limit myself to unessential vdetails of constructionand arrangement.'` v
